Olson, R., Peters, R., Bertram, H., Thomson, B.
A study of the wet deposition of atmospheric pollutants in northeastern Alberta was initiated by Alberta Environment and Atmospheric Environment Service in 1976. The objectives of this ongoing study are to determine changes in the input rate of atmospheric trace substances into sensitive...

Biogeochemical Cycling and Microbial Communities in Native Grasslands:Responses to Climate Change and Defoliation
DownloadSpring 2010
Ongoing climate change has emerged as a major scientific challenge in the current century. Grassland ecosystems are considered net carbon (C) sinks to mitigate climate change. However, they are in turn, influenced by climate change and management practices, providing feedback to climate change...

Takyi, S., Yeung, P., Nyborg, M., Parker, R. W.
In the summers of 1975, 1976, and 1977, several field investigations were carried out to determine the amounts of sulphur deposited in rain, in rain washing off trees, and by direct absorption of SO2 by soil. The impact of this sulphur deposition on soils in the AOSERP study area was also...

Electrodynamics of magnetosphere‐ionosphere coupling and feedback on magnetospheric field line resonances
Download2007
Marchand, Richard, Lu, J. Y., Rankin, Robert, Solomon, Stanley C., Wang, Wenbin, Lei, J., Rae, I. Johnathan
We present a new dynamic model that describes coupling between standing inertial or ion-acoustic-gyroradius-scale shear Alfven waves, compressional modes, and auroral density disturbances. The model is applied to the excitation of field line resonances (FLRs) in dipolar and stretched geomagnetic...

Marchand, Richard, Lu, J. Y., Rankin, Robert, Solomon, Stanley C., Wang, Wenbin, Le, G. M., Wang, J. S., Lei, J., Rae, I. Johnathan
A new interactive M-I coupling model that describes the dynamic interaction between magnetospheric dispersive waves, compressional modes, and auroral electron precipitations is applied to investigate the geomagnetic electromagnetic pulsations observed in Earth's magnetosphere in terms of...

Spence, Harlan, Reeves, Geoffrey D., Zhou, X. Z., Fu, Suiyan, Yuan, C. J., Lui, A. T. Y., Blake, J. B., Rankin, Robert, Hao, Yixin, Baker, D. N., Zong, Qiugang
On 23 November 2012, a sudden dropout of the relativistic electron flux was observed after an interplanetary shock arrival. The dropout peaks at ∼1 MeV and more than 80% of the electrons disappeared from the drift shell. Van Allen twin Probes observed a sharp electron flux dropout with clear...

Evaluation, analysis, and assessment of snowpack and precipitation data from a monitoring network in the AOSERP study area
Download1985
Heidorn, K., Stevens, D., Todd, S., Fellin, P., Davis, C. S.
The data and network operating procedures from the precipitation and snow sampling networks in the AOSERP area of Alberta were reviewed and assessed. The data was first reformatted into NAQUADAT format and then quality assured by several screening procedures including outlier tests, simultaneous...

Finite element modeling of nonlinear dispersive field line resonances: Trapped shear Alfvén waves inside field‐aligned density structures
Download2003-01-01
Marchand, Richard, Rankin, Robert, Wanliss, J. , Tikhonchuk, V. T., Lu, J. Y.
Using a new two- dimensional nonlinear finite element model, we investigate the interaction of dispersive shear Alfven wave ( SAW) field line resonances ( FLRs) and ion acoustic waves in Earth's magnetosphere. We solve the full set of nonlinear reduced MHD equations self- consistently in...
